Abstract: The object of the invention is a pipe duct structure for the installation of HEPAC or other comparable pipe risers in high-rise buildings, comprising a framework (1), dimensioned to floor-to-floor height, into which the pipes (2, 3, 4 and 5) are installed in floor-to-floor height lengths. In order to make solid grouting of the floor slabs between the floors possible also at the pipe duct and to assure the connection of the pipes into continuous risers, regardless of possible faults in alignment between the duct elements installed on different floors, the pipe duct, in accordance with the invention, is distinguished by the fact that the framework (1) has a solid upper level, the pipes (2, 3, 4 and 5) are fitted at least to the said upper level (6) and that the pipe fitting allows a lateral moving of their lower ends.

Abstract: A method and device for operating a conche having a trough (1), on which there is arranged at least one rotor which is driven by at least one electric motor (9) and carries creaming tools which are arranged at an axial distance from one another, distributed around its circumference. The drive motor is controlled by a motor control circuit as a function of a differential signal of a power control loop (22) formed by comparison (6) between a nominal value (7) and an actual value (5) of at least one motor power parameter. 
<??>In order to carry out the conching process in as time-saving a manner as possible it is provided that, during at least one time section, the differential signal of the power control loop (5-8) remains unconsidered for a specific time duration (t). The drive motor (9) can thus accept a maximum motor current and accelerates to the required speed within a very short time.

Abstract: The invention relates to an apparatus which comprises a plurality of tubes made of a first material, which tubes are mounted inside a cylindrical body or shell made of a second material, which second material undergoes differential thermal expansion in relation to the first material of the tubes. The tubes are rigidly secured by their ends to two end members, at least one of which is a floating member due to the fact that it is connected to the shell by means of a flexible ring gasket. The flexible ring-type gasket has inner and outer edges which are clamped to the floating member and to the shell, respectively. The inventive apparatus is useful, for example, in the ultra filtration separation of fine catalyst particles which are in suspension in a hydrocarbon feedstock which feedstock comes from a catalytic cracking unit.

Abstract: The present invention is directed to an electronic ballast device for the control of gas discharge lamps. The device is comprised of a housing unit with electronic circuitry and related components. The device accepts a.c. power and rectifies it into various low d.c. voltages to power the electronic circuitry, and to one or more high d.c. voltages to supply power for the lamps. Both the low d.c. voltages and the high d.c. voltages can be supplied directly, eliminating the need to rectify a.c. power. The device switches a d.c. voltage such that a high frequency signal is generated. Because of the choice of output transformers matched to the high frequency (about 38 kHz) and the ability to change frequency slightly to achieve proper current, the device can accept various lamp sizes without modification. The ballast can also dim the lamps by increasing the frequency. The device can be remotely controlled. <IMAGE>
